rcsdiff(1)                       DG/UX 5.4.2                      rcsdiff(1)


NAME
       rcsdiff - compare RCS revisions

SYNOPSIS
       rcsdiff [ -ksubst ] [ -q ] [ -rrev1 [ -rrev2 ] ] [ -Vn ] [ -xsuffixes
       ] [ diff options ] file ...

DESCRIPTION
       rcsdiff runs diff(1) to compare two revisions of each RCS file given.

       Pathnames matching an RCS suffix denote RCS files; all others denote
       working files.  Names are paired as explained in ci(1).

       The option -q suppresses diagnostic output.  Zero, one, or two
       revisions may be specified with -r.  The option -ksubst affects
       keyword substitution when extracting revisions, as described in
       co(1); for example, -kk -r1.1 -r1.2 ignores differences in keyword
       values when comparing revisions 1.1 and 1.2.  To avoid excess output
       from locker name substitution, -kkvl is assumed if (1) at most one
       revision option is given, (2) no -k option is given, (3) -kkv is the
       default keyword substitution, and (4) the working file's mode would
       be produced by co -l.  See co(1) for details about -V.  and -x.
       Otherwise, all options of diff(1) that apply to regular files are
       accepted, with the same meaning as for diff.

       If both rev1 and rev2 are omitted, rcsdiff compares the latest
       revision on the default branch (by default the trunk) with the
       contents of the corresponding working file.  This is useful for
       determining what you changed since the last checkin.

       If rev1 is given, but rev2 is omitted, rcsdiff compares revision rev1
       of the RCS file with the contents of the corresponding working file.

       If both rev1 and rev2 are given, rcsdiff compares revisions rev1 and
       rev2 of the RCS file.

       Both rev1 and rev2 may be given numerically or symbolically.

EXAMPLE
       The command

               rcsdiff  f.c

       compares the latest revision on the default branch of the RCS file to
       the contents of the working file f.c.

ENVIRONMENT
       RCSINIT
              options prepended to the argument list, separated by spaces.
              See ci(1) for details.

DIAGNOSTICS
       Exit status is 0 for no differences during any comparison, 1 for some
       differences, 2 for trouble.
